I stuck my penis in my girlfriends vagina but that was it. No sex. Stuck it in and took it out. There was some precum but I wiped it off before going in but I don't know if any more came out. I did masturbate before but I'm pretty sure I peed and I know I took a shower right after masturbating and before I stuck it in. And I always get as much out of my urethra after ejeculating as I can. We are 15. Could she be pregnant? What are the odds that she is?

Yes, she could be pregnant. You put your penis in her vagina, so you actually DID have sex.

Are you prepared to be a father? Do you have a good job? Do you understand the danger you place her in if she does get pregnant?

You're an idiot kid playing adult games and you are asking for problems by doing things that you have no understanding of.
